QTranslate is a free translator for Windows. With this small
utility, you simply select the text you want to translate and then
press the hot key (
Ctrl+Q
to show translation in the popup window or
Double Ctrl
click to show the translation in the main window). QTranslate also
has the ability to speak text
Ctrl+E
and perform a dictionary search
Ctrl+Shift+Q
. Also, you can open the main window and type text manually.

Note! QTranslate translates
text by using online translation services, so you need an Internet
connection.
